Semiconductor memory module e.g. fully buffered dual inline memory module, has two sets of memory devices arranged in two rows on module board, and third set of memory devices arranged in third row which extends between two rows, on board

摘要

The module has a module board (MP) with two ends (EMP1, EMP2) running along a direction. Three sets of semiconductor memory devices (P1-P18) are provided, and each device has two ends with different lengths. The two sets of devices are arranged in two rows (R1, R2) on the board (MP), where the rows extend along the two ends of the board and the ends of the devices of the two sets run along the direction. The third set of devices is arranged in a third row (R3) on the board, and the third row extends between the two rows, and the ends of the devices of the third row run along the direction.
